MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 385,377, dated July 3, 1888.

Application tiled September 16, 1887. Serial No. 249,884. (No model.)

To all whom it may concern/.

Be it known that 1, JOHN F. Sononrrns, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new cross-section, and Fig. 4 a detail view, of my devices arranged to convert an oscillating movement into a rotary movement, as for driving street-cars and for other purposes; and Fig. 5 is a sectional elevation, and Fig. 6 a sectional plan, of my device for driving a pump.

Corresponding referential characters in the several figures of the drawings designate like parts.

A broad-faced spur-wheel, 1, is pivotally secured upon a fulcrum-pin of frame 2, and the upwardly-projecting hub of this spurwheel 1 has secured a crosshandle, 3, to be operatedby the hands or feet for imparting an oscillating movement to said wheel. At diametrical] y-opposite positions in relation to said wheel 1 the frame 2 is provided with vertical hubs 4.,that are bored out and screw-th readed one for a right-hand and the other one for a lefthand screw, 5, a pinion, 6, being mounted upon the upper end of each such screw 5, the teeth of which pinions 6 will mesh with the teeth of wheel 1. With this arrangement a rotating movement of wheel 1 will also rotate screws 5, which, having one a right and the other a left screw-thread,will be moved simultaneously in vertically-opposite directions,whereby with an oscillating movement of wheel 1 these screws 5 will move up and down in alternate order.

Upon the lower end of each screw 5 is secured a sleeve, 7, forming the socket-bearing for the ball-shaped head of a rod, 8, that to its lower end has secured a bifurcated head, 9, coupling with the end of a lever, 10. The opposite ends of these levers 10 are vertically slotted, and are pivoted upon a shaft or axle. 11, having rigidly-mounted ratchet-wheels 12 inside of the slots of levers 10, and each such lever is provided with a pawl, 13, also inside of such slots,pushed into engagement with the ratchet-wheel by a spring. 14, which pawls alternately engaging the teeth of the ratchetwheels, the oscillation ofthe two levers 10 alternately in opposite directions will transmit a continuous rotary movement to shaft or axle 11. By this device the oscillation of wheel 1 will transmit a reciprocating movement of screws 5 in alternate opposite directions,which will oscillate levers 10,that again, by their alternate pawl-and-ratchct-whecl action, will rotate shaft or axle 11.

In Fig. 5 the parts are the same, excepting that rods 8 are coupled with the plunger-rods 15 of a double pump, 16, which pump may be of any ordinary construction. The oscillation of lever 3 by hand or feet will simultaneously reciprocate the pump-plungers in alternate dt rections, whereby the pump will throw out a continuous stream of water.

What I claim is-- The combination, with wheel 1, provided with handle 3, two opposi tcl y-threaded screws, 5, with pinions 6, and with connecting-rods 8. of levers 10, pivotedon shaft 11, and provided with ratchet-wheels 12, mounted upon such shaft 11, all substantially as described, to operate as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN F. SOHOETTES.
